-3(3x+15)-(10+x) = 35 help me find x please
Reika [66]
X=-9. To do this equation you had to do a multi-step problem solver teqnique. But I would recommend Khan Academy for any questions. My best advice would be for that. Or you can just try to simplify the equation down as much as possible. To do so, you'd have to multiply the first parentheses by -3. Which would equal: (-9x+-65) -(10+x) =35. Next you will add 65 to each side. But always remember if you to something on this side, you must always do it on the other side over the equal sign. Which would equal to: -9-(10+x) =100. So from here you will subract 10 to eliminate the number 10. Like so: -9x+x=90. So from here, you will just add the two x's together because, in math simplifying in the most important thing ever!: -10x/10=90/10. (The parentheses mean division btw) Then after dividing you will get x=-9. Hope that helps and after getting this through your head it's a piece of cake. Good luck
